Again, we do this the old way, by hand&#8230;. Quite a bit of work to do 4 gliders with exchangeable outer wings, and a nice pile of foam as a result. Unfortunately I didn&#8217;t get a photo of all the foam as we distributed it among the team to avoid the pileup in the workshop&#8230;.<\/p>\n<p><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" data-attachment-id=\"80\" data-permalink=\"https:\/\/www.lefevere.eu\/modellflug\/2018\/01\/17\/cutting-wing-and-elevator-cores\/img_6110\/#main\" data-orig-file=\"https:\/\/i0.wp.com\/www.lefevere.eu\/modellflug\/wp-content\/uploads\/2018\/01\/IMG_6110.jpg?fit=3264%2C2448&amp;ssl=1\" data-orig-size=\"3264,2448\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;2.2&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;iPhone 6&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;1513788568&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;4.15&quot;,&quot;iso&quot;:&quot;32&quot;,&quot;shutter_speed&quot;:&quot;0.0076923076923077&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;1&quot;}\" data-image-title=\"IMG_6110\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/www.lefevere.eu\/modellflug\/wp-content\/uploads\/2018\/01\/IMG_6110.jpg?fit=510%2C383&amp;ssl=1\" class=\"alignnone wp-image-80 size-medium\" src=\"https:\/\/i0.wp.com\/www.lefevere.eu\/modellflug\/wp-content\/uploads\/2018\/01\/IMG_6110-300x225.jpg?resize=300%2C225\" alt=\"\" width=\"300\" height=\"225\" srcset=\"https:\/\/i0.wp.com\/www.lefevere.eu\/modellflug\/wp-content\/uploads\/2018\/01\/IMG_6110.jpg?resize=300%2C225&amp;ssl=1 300w, https:\/\/i0.wp.com\/www.lefevere.eu\/modellflug\/wp-content\/uploads\/2018\/01\/IMG_6110.jpg?resize=768%2C576&amp;ssl=1 768w, https:\/\/i0.wp.com\/www.lefevere.eu\/modellflug\/wp-content\/uploads\/2018\/01\/IMG_6110.jpg?resize=1024%2C768&amp;ssl=1 1024w, https:\/\/i0.wp.com\/www.lefevere.eu\/modellflug\/wp-content\/uploads\/2018\/01\/IMG_6110.jpg?w=1530&amp;ssl=1 1530w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/> <img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" data-attachment-id=\"81\" data-permalink=\"https:\/\/www.lefevere.eu\/modellflug\/2018\/01\/17\/cutting-wing-and-elevator-cores\/img_6184\/#main\" data-orig-file=\"https:\/\/i0.wp.com\/www.lefevere.eu\/modellflug\/wp-content\/uploads\/2018\/01\/IMG_6184.jpg?fit=3264%2C2448&amp;ssl=1\" data-orig-size=\"3264,2448\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;2.2&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;iPhone 6&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;1515755639&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;4.15&quot;,&quot;iso&quot;:&quot;50&quot;,&quot;shutter_speed&quot;:&quot;0.03030303030303&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;1&quot;}\" data-image-title=\"IMG_6184\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/www.lefevere.eu\/modellflug\/wp-content\/uploads\/2018\/01\/IMG_6184.jpg?fit=510%2C383&amp;ssl=1\" class=\"alignnone wp-image-81 size-medium\" src=\"https:\/\/i0.wp.com\/www.lefevere.eu\/modellflug\/wp-content\/uploads\/2018\/01\/IMG_6184-300x225.jpg?resize=300%2C225\" alt=\"\" width=\"300\" height=\"225\" srcset=\"https:\/\/i0.wp.com\/www.lefevere.eu\/modellflug\/wp-content\/uploads\/2018\/01\/IMG_6184.jpg?resize=300%2C225&amp;ssl=1 300w, https:\/\/i0.wp.com\/www.lefevere.eu\/modellflug\/wp-content\/uploads\/2018\/01\/IMG_6184.jpg?resize=768%2C576&amp;ssl=1 768w, https:\/\/i0.wp.com\/www.lefevere.eu\/modellflug\/wp-content\/uploads\/2018\/01\/IMG_6184.jpg?resize=1024%2C768&amp;ssl=1 1024w, https:\/\/i0.wp.com\/www.lefevere.eu\/modellflug\/wp-content\/uploads\/2018\/01\/IMG_6184.jpg?w=1530&amp;ssl=1 1530w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>We build our wings and elevator around a foam core, covered with wood and then glass, before spray painting them.
